I set up a lot of these on bows as they are the primary rest I recommend for hunters. I always tie in nock point first before installing the rest. I set the nock pointup for starterson one cams usually at 3/8" nock high with perfect zero being level with the bottom of the berger hole. Everyone measures nock height differently but this is how I do it in the shop when setting up bows. I actually setup 3 bows tonight like this. Once this is done I install the rest so that the bottom of the rest hole is level with the bottom of the berger hole, and on Mathews centershot is usually around 13/16's. Hope this helps.
